SPECIFICATION forming part of Letters Patent No. 694,134, dated February25, 1902.

'Application filed November 16,1901. ASerial No. 82,546. (No model.)

To @ZZ whom, it Wray concern:

Beit known that I, JOSEPH L. CAMPBELL, a citizen of the United States ofAmerica, residing atButler,in the county ofButlerand State yofPennsylvania, have invented certain new and useful Improvements inRail-Joints, of which the following is a specificatiomreference beinghad therein to the accompanying drawings.

This invention relates to certain new and luseful improvements inmetallic ties and fastenings for securing the rails thereto,and has forits main object to construct a cheap metallic tie and provide inconnection therewith novel and effective means for securing the railsfirmly in position upon the ties.

To this end the invention resides in the novel combination andarrangementof parts to be hereinafter more fully described, andspecifically pointed out in the claims.

In describing the invention in detail refery'ence is had to theaccompanying drawings, forming a part of this specification, and whereinlike numerals of reference indicate 'corresponding parts throughout theseveral views, in which- Figure 1 is a side elevation of a portion ofiny improved tie and fastening device, showing the rails securedtherein, the latter being in section. Fig. 2 is a top plan view of Fig.3 is a top plan view of a portion of the tie with the rail and fasteningdevice removed. Fig. 4 is a detail side elevaltion of the insideclamping-block. Fig. 5 is a like view of the out-side clamping-block.Fig. 6 is an underneath plan view of the inside clamping-block. Fig. 7is a like view of the outside clamping-block. Fig. 8 is a detailperspective View of the pivoted lockingpawl for holding the insideclamping-block in position. Fig. 9 is an edge view of the same. Fig. 10is a plan view of the securingkey for holding the outside clamping-blockin position.

My improved tie is substantially in the form of an inverted T inv endview or crosssection, comprising a base 1 and a head 2. In its upperface this tie is recessed adjacent to each end thereof,where the rails 3are adapted to rest, the recesses 4 5, extending across the head 2 at anangle, and the portions 6 of the tie betweeu'the recesses 4 and 5 beingadapted to receive the base of .the rail 3. The rail 3 is securelylocked in position on the tie by meansv of the outside clamping-block 7,which has a tongue 8, adapt-ed to fit in the groove 9, provided thereforin the head 2 of the tie. This clamping-block 7 carries integral studsor pins 10, which project outwardly from the flange 11, carried by theblock 7, and are adapted to engage in apertures (not shownlwhich areprovided therefor in the web of the rail 3. The clamping-block 7 has itsinner edge 12 at an incline, this incline andthe bevel given theretoconforming to the angular wall of the portion 6, upon which the railrests. The clamping-block 7 is held in position in the recess 5 by meansof the key 14, which is inserted in the keyway l5, provided therefor intheunderneath face of the block 7 and in the head of the tie. Thiskeyway extends at an angle across the block and tie, as shown. To engagethe inner face of the rail-web, I provide a clamping-block 16, which hasa tongue 17 on its outer end which engages in the groove 18, providedtherefor in the head 2 of the tie. This block 16 also has a tongue 19,the outer face of which is at an angle to the block and which engagesand conformsto the angular wall of the portions 6 of the tie. The tie isrecessed underneath the block 16, and in this recess 2O is mounted alocking-pawl 21, which is secured upon a short shaft 22, that isjournaled in the socket 23 in the tie. This locking-pawl 21 is providedwith a keyway 24, which is in registration with the keyway 25, providedin the side of the tie and through which a suitable key 26 may beinserted for operating the locking-pawl so as to throw the same into alocked position, as shown in Fig. 1, or to operate the same so as tomove the pawl within its recess and permit the removal of the clamping-block 16.

, In practice the clamping-block 7 is placed in position and securelylocked by its key 14 when the rail 3 is placed in position against saidclamping-block, and the clamping-block 16 is then slid into the openingtransversely of the tie, and after being adjusted to position thelocking-pawl 21 is thrown upwardly into the recess 27, provided thereforin the IDO underneath face of the block 1G. To remove thereof at anangle, of a pair of clamping-' blocks fitted in said recesses andadapted to embrace opposite sides of the rail, pins carried by one ofsaid clamping-blocks, a key for securing one of the blocks in position,and a.

pivoted locking-pawl for securing the other block in position,substantially as described.

2. In combination with a metallic tie having recesses in the upper facethereof, of a pair of clamping-blocks mounted in said recesses, a keyfor securing one of said clamping-blocks in position, and a pivotedlookin gpawl for securing the other of said, blocks, substantially asdescribed.

3. In combination with a metallic tie, a pair of clamping-blocks adaptedto embrace opposite sides of the rail for holdingsame to the tie, a keyfitting in the angular keyway extending through one of the blocks andthrough the tie, and a locking-pawl mounted in the tie and adapted toengage in the recess in the other clamping-block for securing same inposition, substantially as described.

4. In combination with a metallic tie having recesses in its upper face,of a pair of clamping-blocks tted in said recesses and provided withtongues which engage in grooves in the tie, a key for securing one ofthe blocks in position, and a pivoted lockingpawl mounted in therecesses of the tie and adapted to engage in the recess of the otherclamping-block for secu ring same in position, substantially asdescribed.

In testimony whereof I affix my signature in the presence of twowitnesses.
